... Measuring Center: The Median The median M is the midpoint of a distribution, the number such that half of the observations are smaller and the other half are larger. To find the median of a distribution: 1)Arrange all observations from smallest to largest. 2)If the number of observations n is odd, ...

... Figure 8.2 summarizes our results. For each sample, we have drawn a graph on the right-hand side of Fig. 8.2. The dot represents the sample mean, x , in thousands of dollars, and the horizontal line represents the corresponding 95.44% confidence interval. Note that the population mean, μ, lies in th ...
